+NAME
+ lbasename -- return pointer to last component of a pathname
+
+SYNOPSIS
+ char *lbasename (const char *name)
+
+DESCRIPTION
+ Given a pointer to a string containing a typical pathname
+ (/usr/src/cmd/ls/ls.c for example), returns a pointer to the
+ last component of the pathname ("ls.c" in this case). The
+ returned pointer is guaranteed to lie within the original
+ string. This latter fact is not true of many vendor C
+ libraries, which return special strings or modify the passed
+ strings for particular input.
+
+ In particular, the empty string returns the same empty string,
+ and a path ending in '/' returns the empty string after it.
